INTRODUCTION / INTRODUCCIÓN
Page 3 — English
WARNING:
Read and understand all instructions. Failure
to follow all instructions listed below, may result
in electric shock, fire and/or serious personal
injury.
READ ALL INSTRUCTIONS
Know your tool. Read the operator’s manual
carefully. Learn the saw’s applications and lim-
itations as well as the specific potential hazards
related to this tool.
Kickback may occur when the nose or tip of
the guide bar touches an object, or when the
wood closes in and pinches the saw chain in
the cut. Tip contact in some cases may cause a
lightning-fast reverse reaction, kicking the guide
bar up and back toward the operator. Pinching
the saw chain along the top of the guide bar
may push the guide bar rapidly back toward the
operator. Either of these reactions may cause
you to lose control of the saw, which could result
in serious personal injury. Do not rely exclusively
upon the safety devices built into the saw. As a
chain saw user, you should take several steps
to keep your cutting jobs free from accident or
injury.
• With a basic understanding of kickback,
you can reduce or eliminate the element
of surprise. Sudden surprise contributes to
accidents.
• Keep a good firm grip on the saw with both
hands when the engine is running. Place your
right hand on the rear handle and your left
hand on the front handle with your thumbs
and fingers encircling the chain saw handles.
A firm grip together with a stiff left arm will
help you maintain control of the saw if kick-
back occurs.
• Make sure that the area in which you are
cutting is free from obstructions. DO NOT
let the nose of the guide bar contact a log,
branch, fence, or any other obstruction that
could be hit while you are operating the saw.
• Cut at high engine speeds. Always cut
with the engine running at full speed. Fully
squeeze the throttle trigger and maintain a
steady cutting speed.
• Do not overreach or cut above chest height.
• Follow the manufacturer’s sharpening and
maintenance instructions for the saw chain.
• Only use replacement bars and chains spec-
ified by the manufacturer or the equivalent.
Do not operate a chain saw with one hand.
Serious injury to the operator, helpers, bystand-
ers, or any combination of these persons may
result from one-handed operation. A chain saw
is intended for two-handed use.
Do not operate a chain saw when you are
fatigued. Fatigue causes carelessness. Never
operate a chain saw when you are tired or under
the influence of medication, drugs, or alcohol.
Use safety footwear. Wear snug-fitting cloth-
ing, protective gloves, and eye, hearing, and
head protection devices.
Heavy protective clothing may increase oper-
ator fatigue, which could lead to heat stroke.
During weather that is hot and humid, heavy
work should be scheduled for early morning
or late afternoon hours when temperatures are
cooler.
Do not stand on any unstable surface while
using the chain saw, such as ladders, scaffolds,
trees, etc.
Use caution when handling fuel. Move the
chain saw at least 30 feet from the fueling point
before starting the engine.
Do not allow other persons to be near the
chain saw when starting or cutting with the
chain saw. Keep bystanders and animals out
of the work area.
Do not start cutting until you have a clear
work area, secure footing, and a planned retreat
path from the falling tree.
Keep all parts of your body away from the
saw chain when the engine is running.
Always carry the chain saw with the engine
stopped and the brake engaged, the guide bar
and saw chain to the rear, and the muffler away
from your body. When transporting the chain
saw, use the appropriate guide bar scabbard.
GENERAL SAFETY RULES
Page 4 — English
WARNING:
The warnings, labels, and instructions found
in this section of the operator’s manual are for
your safety. Failure to follow all instructions may
result in serious personal injury.
Do not cut vines and/or small underbrush (a
diameter of less than 3 in.).
Muffler surfaces are very hot during and after
operation of the chain saw; keep all body parts
away from the muffler. Serious burns may occur
if contact is made with the muffler.
Always hold the chain saw with both hands
when the engine is running. Use a firm grip
with thumbs and fingers encircling the chain
saw handles.
Never let anyone use the chain saw who
has not received adequate instructions in its
proper use. This applies to rentals as well as
privately owned saws.
Before you start the engine, make sure the
saw chain is not contacting any object.
Do not operate a chain saw that is damaged,
improperly adjusted, or not completely and
securely assembled. Be sure that the saw chain
stops moving when the throttle control trigger
is released.
Shut off the engine before setting the chain
saw down. Do not leave the engine running
unattended. As an additional safety precaution,
apply the chain brake prior to setting down the
saw.
Use extreme caution when cutting small-size
brush and saplings because slender material
may catch the saw chain and be whipped
toward you or pull you off balance.
When cutting a limb that is under tension,
be alert for springback so that you will not be
struck when the tension in the wood fibers is
released.
Keep the handles dry, clean, and free of oil or
fuel mixture.
Do not start or operate the engine in a con-
fined space, building, near open windows,
or in other unventilated space where dan-
gerous carbon monoxide fumes can collect.
Carbon monoxide, a colorless, odorless,
and extremely dangerous gas, can cause
unconsciousness or death.
Do not operate a chain saw in a tree unless
you have been specifically trained to do so.
Do not cut from a ladder; this is extremely
dangerous.
All chain saw service, other than the items
listed in the instruction manual and all main-
tenance, should be performed by competent
chain saw service personnel. (For example, if
improper tools are used to remove the flywheel
or if an improper tool is used to hold the flywheel
in order to remove the clutch, structural damage
to the flywheel could occur and subsequently
could cause the flywheel to burst.)
Always have a fire extinguisher available
when using chain saw.
Use only the replacement guide bars and low
kickback chains specified for the saw.
Do not adapt the powerhead to a bow guide
or use it to power any attachments or devices
not listed for the saw.
The gas powered saw (or electrically pow-
ered saw) is classified by CSA as a Class 1C
(or Class 2C) saw. It is intended for infrequent
use by homeowners, cottagers, and campers,
and for such general applications as clearing,
pruning, cutting firewood, etc. It is not intended
for prolonged use. Prolonged periods of opera-
tion can cause circulatory problems in the user’s
hands due to vibration.
Save these instructions. Refer to them
frequently and use to instruct other users. If
you loan someone this tool, loan them these
instructions also.
GENERAL SAFETY RULES
SPECIFIC SAFETY RULES
Page 5 — English
SPECIFIC SAFETY RULES
Wear snug-fitting clothing. Always wear heavy
long pants, boots, and gloves. Do not wear
jewelry, short pants, sandals, or go barefoot.
Do not wear loose fitting clothing, which could
be drawn into the engine or catch the chain
or underbrush. Wear overalls, jeans, or chaps
made of cut-resistant material or ones that
contain cut-resistant inserts. Secure hair so that
it is above shoulder level.
Wear non-slip safety footwear and heavy-
duty gloves to improve your grip and to protect
your hands.
Wear eye protection with side shields marked
to comply with ANSI Z87.1, along with hear-
ing and head protection, when operating this
equipment.
Keep bystanders and animals out of the work
area. Do not allow other persons to be nearby
during starting or cutting with the chain saw.
NOTE: The size of the work area depends on the
job being performed as well as the size tree or
workpiece involved. For example, felling a tree
requires a larger work area than making other
cuts (i.e., bucking cuts, etc.).
Keep SAFE-T-TIP™ anti-kickback nose guard
properly mounted on the guide bar to prevent
rotational kickback.
Follow the sharpening and maintenance
instructions for the saw chain.
Never operate a chain saw that is damaged,
improperly adjusted, or is not completely
and securely assembled. Be sure that the saw
chain stops moving when the throttle control
trigger is released. If the saw chain moves at
idle speed, the carburetor may need adjusting.
Refer to Adjusting the Carburetor in the Main-
tenance section of this manual. If the saw chain
still moves at idle speed after adjustment has
been made, contact a qualified service center
for adjustment and discontinue use until the
repair is made.
This product is intended for infrequent use
by homeowners and other occasional users
for general applications such as clearing, prun-
ing, cutting firewood, etc. It is not intended for
prolonged use. Prolonged periods of operation
can cause circulatory problems in the user’s
hands due to vibration. For such use, it may be
appropriate to use a product having an anti-
vibration feature.
REFUELING (DO NOT SMOKE!)
To reduce the risk of fire and burn injury,
handle fuel with care. It is highly flammable.
Mix and store fuel in a container approved for
gasoline.
Mix fuel outdoors where there are no sparks
or flames.
Select bare ground, stop the engine, and
allow it to cool before refueling.
Loosen the fuel cap slowly to release pressure
and to keep fuel from escaping around the cap.
Tighten the fuel cap securely after refueling.
Wipe spilled fuel from the unit. Move 30 feet
away from refueling site before starting engine.
Never attempt to burn off spilled fuel under
any circumstances.
KICKBACK
Kickback is a dangerous reaction that can
lead to serious injury. Do not rely only on the
safety devices provided with the saw. As a
chain saw user, you must take special safety
precautions to help keep your cutting jobs free
from accident or injury. See the General Safety
Rules and Operation sections of this manual
for added information on kickback and how to
avoid serious personal injury.
CAUTION: User not to use a replacement saw
chain unless it has been designated as meet-
ing the kickback performance requirements in
ANSI/OPEI B175.1-2012 on that specific power
head, or has been designated as low-kickback
replacement saw chain in accordance with
ANSI/OPEI B175.1-2012

little lubricant will cause overheating shown by
smoke coming from the chain and/or discolor-
ation of the bar. Lubrication can be increased or
decreased by turning (up to 1/4 turn maximum)
the adjustment screw located on the bottom of
the crankcase with the screwdriver end of the
included combination wrench.
WARNING:
NEVER adjust the automatic oiler system when
the engine is running. Failure to do so could
cause serious personal injury.

ADDING BAR AND CHAIN LUBRICANT
See Figure 3.
Use a bar and chain lubricant designed for lubri-
cating chain saw chains. They are formulated to
extend bar and chain life by protecting against
wear and reducing friction and heat. Chain saw
should use approximately one tank of lubricant
per tank of fuel.

Carefully pour the bar and chain lubricant into
the oil tank.
Fill the oil tank every time you fuel the engine.
OPERATING THE CHAIN BRAKE
See Figures 4 - 5.
Check the operating condition of the chain brake
prior to each use.
Using the back of your left hand, engage the
chain brake by pushing the chain brake lever/
hand guard toward the bar while the chain is
rotating rapidly.
Reset the chain brake back into the RUN posi-
tion by grasping the top of the chain brake lever/
hand guard and pulling toward the front handle
until you hear a click.
WARNING:
If the chain brake does not stop the chain imme-
diately, or if the chain brake will not stay in the
run position without assistance, take the saw to
a qualified service center for repair prior to use.
STARTING THE ENGINE
See Figures 6 - 10.
The starting method differs depending on whether
the engine is cold or warm.
WARNING:
Keep your body to the left of the chain line.
Never straddle the saw or chain, or lean over
past the chain line.
Place the chain saw on level ground and ensure
that no objects or obstructions are in the imme-
diate vicinity that could come in contact with the
bar and chain. To prevent rapid dulling of the
chain, do not allow the bar and chain to contact
dirt on the ground.
Hold the front handle firmly with your left hand
and put your right foot onto the base of the rear
handle.

STOPPING THE ENGINE
See Figures 11 - 12.
Release the throttle trigger and let the engine
return to idle. To stop the engine, move the on/
stop switch to the STOP ( ) position. Do not put
the chain saw on the ground when the chain is still
moving. For additional safety, set the chain brake
when the saw is not in use.
In the event that the on/stop switch will not stop the
saw, pull the choke knob out to the fully extended
position (FULL CHOKE / ) and engage chain
brake to stop the engine. If the on/stop switch will
not stop the saw when set to the STOP position,
have the on/stop switch repaired before using the
chain saw again to prevent unsafe conditions or
serious injury.
NOTE: When you are finished using the saw,
always relieve tank pressure by loosening, then
retightening, the chain oil and fuel mix caps. Allow
the engine to cool before storing.
ADJUSTING IDLE SPEED
See Figure 13.
WARNING:
The chain will move around the guide bar when
adjusting the idle speed. Wear all protective
clothing and keep all bystanders, children, and
pets at least 50 ft. away. Make adjustments
with the unit supported on a stable surface so
that the chain/guide bar does not contact the
ground or any object. Keep all parts of your
body away from the chain/guide bar and muf-
fler. Failure to follow these instructions could
result in serious personal injury.
If the engine starts, runs, and accelerates,
but will not idle, turn the idle speed screw “T”
clockwise to increase idle speed.
If the chain turns at idle, turn the idle speed
screw “T” counterclockwise to reduce the
idle RPM and stop the chain movement. If the
saw chain still moves at idle speed, contact
a qualified service center for adjustment and
discontinue use until the repair is made.

WARNING:
THE SAW CHAIN SHOULD NEVER TURN AT

clockwise to reduce the idle RPM and stop the
chain, or contact a qualified service center for
adjustment and discontinue use until the repair
is made. Serious personal injury may result from
the saw chain turning at idle.
PULL AND PUSH
See Figure 14.
The reaction force of the saw is always opposite to
the direction the chain is moving. Thus, the operator
must be ready to control the PULL when cutting
on the bottom edge of the bar and the PUSH when
cutting along the top edge.
NOTE: The chain saw has been fully factory tested.
It is normal to find some slight lubricant residue
on the saw.
WARNING:
KICKBACK occurs when the moving chain
contacts an object at the upper portion of the
tip of the guide bar or when the wood closes in
and pinches the saw chain in the cut. Contact
at the upper portion of the tip of the guide bar
can cause the chain to dig into the object and
stop the chain for an instant. The result is a
lightning-fast reverse reaction which kicks the
guide bar up and back toward the operator. If
the saw chain is pinched along the top of the
guide bar, the guide bar can be driven rapidly
back toward the operator. Either of these reac-
tions can cause loss of saw control, which can
result in serious injury.
Do not rely exclusively upon the safety devices
built into the saw. As a chain saw user, you
should take steps to keep your cutting jobs
free from accident or injury. See General Safety
Rules for more details.

KICKBACK PRECAUTIONS
See Figures 15 - 16.
Rotational kickback occurs when the moving chain
contacts an object at the Kickback Danger Zone of
the guide bar. The result is a lightning-fast reverse
reaction, which kicks the guide bar up and back
towards the operator. This reaction can cause loss
of control, which can result in serious injury.
PREPARING FOR CUTTING
PROPER GRIP ON HANDLES
See Figure 17.
See General Safety Rules for appropriate safety
equipment.
Wear non-slip gloves for maximum grip and
protection.
Hold the saw firmly with both hands. Always
keep your left hand on the front handle and your
right hand on the rear handle so that your body
is to the left of the chain line.
WARNING:
Never use a left-handed (cross-handed) grip or
any stance that would place your body or arm
across the chain line.
Maintain a proper grip on the saw whenever the
engine is running. The fingers should encircle
the handle and the thumb is wrapped under the
handlebar. This grip is least likely to be broken
by a kickback or other sudden reaction of the
saw. Any grip in which the thumb and fingers
are on the same side of the handle is dangerous
because a slight kick of the saw can cause loss
of control.
PROPER CUTTING STANCE
See Figure 18.
WARNING:
Always use the proper cutting stance described
in this section. Never kneel when using the
chain saw, except when felling a tree as illus-
trated in Figure 23. Kneeling could result in
loss of stability and control of the chain saw,
resulting in serious personal injury.

Keep your body to the left of the chain line.
Keep your thumb on underside of handlebar.
WORK AREA PRECAUTIONS
See Figure 19.
Cut only wood or materials made from wood;
no sheet metal, no plastics, no masonry, no
non-wood building materials.
Never allow children to operate the saw. Allow
no person to use this chain saw who has not
read this operator’s manual or received ade-
quate instructions for the safe and proper use
of this chain saw.
Keep everyone – helpers, bystanders, children,
and animals, a SAFE DISTANCE from the
cutting area. During felling operations, the safe
distance should be a least twice the height of the
largest trees in the felling area. During bucking
operations, keep a minimum distance of 15 feet
between workers.
Always cut with both feet on solid ground to
prevent being pulled off balance.
Do not cut above chest height as a saw held
higher is difficult to control against kickback
forces.
Do not fell trees near electrical wires or build-
ings. Leave this operation for professionals.
Cut only when visibility and light are adequate
for you to see clearly.
OPERATION
WARNING:
DO NOT operate the throttle trigger with your
left hand and hold the front handle with your
right hand. Never allow any part of your body
to be in the chain line while operating a saw.
CHAIN LINE
Page 20 — English
BASIC OPERATING/CUTTING
PROCEDURES
Practice cutting a few small logs using the following
technique to get the “feel” of using the saw before
you begin a major sawing operation.
Take the proper stance in front of the wood with
the saw idling.
Accelerate the engine to full throttle just before
entering the cut by squeezing the throttle trigger.
Begin cutting with the saw against the log.
Keep the engine at full throttle the entire time
you are cutting.
Allow the chain to cut for you; exert only light
downward pressure. Forcing the cut could result
in damage to the bar, chain, or engine.
Release the throttle trigger as soon as the cut is
completed allowing the engine to idle. Running
the saw at full throttle without a cutting load can
result in unnecessary wear to the chain, bar, and
engine.
Do not put pressure on the saw at the end of
the cut.
FELLING TREES
HAZARDOUS CONDITIONS
See Figures 20 - 23.
WARNING:
Do not fell trees during periods of high wind or
heavy precipitation. Wait until the hazardous
weather has ended.
